Description

TObject is the parent root class for all classes in Object Pascal. If a class has no parent class explicitly declared, it is dependent on TObject. TObject introduces class methods that deal with the class' type information, and contains all necessary methods to create an instance at runtime, and to dispatch messages to the correct method (both string and integer messages).
